How to block computer from accessing network completely...

Here's the issue - one of my roommates's girlfriend is leeching our internet daily. She has her own place but doesn't pay for cable/internet there because she gets it for free here. The router is a Linksys WGT624 v3 router. I've asked repeatedly for him to not allow this, but it continues, and I'm at my wit's end. My first thought was to disable the DHCP server and enable static IPs, but the roommate knows enough that he would probably be able to get around that. Looking at the administration area, I was able to restrict the WIRELESS access to specified MAC addresses, but she usually plugs in. Router can be changed or upgraded to accommodate me and my plans for it - but I need a resolution soon (today/tomorrow)

I basically need to know how to configure this router to either A)allow only specified wired mac addresses or B)disable network connectivity for a certain mac address OR I need to know of a router that can handle my requests..

Yes I do - Issues that in no way relate to the current problem at hand. Because it is a dually signed lease, I cannot kick him out, and nor can I leave the house. Therefore, she will be paying for her share of the bills or she will stop using them. She is not a casual visitor. She is here..every night...every day..taking showers, using my washer and dryer, and so forth. She has the apartment because her parents are paying for it.

Regardless of whether or not you agree with me, I need help with this. I have offered her plenty of chances to make agreements on utility usage and she has declined all. It is time to take action here.

If you don't want to help, that is fine. No further comments are necessary.

sounds like your just right. i wouldnt like that if someone done that to me

I'm an idiot (I've been so tired lately). It is a netgear. My old Linksys died on me a couple of weeks ago and I had had it forever, so I guess I'm still referring to it. It is a Netgear router, but like I said - if it can't perform the required functions, I will spend money to get one that can.

I actually did think about that, but then didn't because the IPs are dynamic. Therefore, all it would require is a simple /renew and she'd be back on. Static IPs are out of the question because it's easy to get around....This is so frustrating. I just wish I didn't have to do this..

I dont see a way of doing this unless she has her own laptop or something she brings round.

If she does, then its simple. In you LAN settings on your NETGEAR admin panel, change the IP range your DHCP can distribute to ***.***.*.2 - ***.***.*.4 (if you have 2 computers) then when she connects her's up an ip wont be given unless the lease has expired on one of your machines.

GENIUS! (Yes, she does bring her laptop..usually plugs in but sometime uses wireless..I've got the wireless blocked but not the wired)

I'll set reserved IPs for the 4 computers of the actual housemates..then I'll set the DHCP server to only give out those specific 4 IPs...so when she tries to connect, it will just sit in limbo forever...
I think that should do it.

Personally I'd add a reservation for the laptops MAC address and null route as I suggested above, else you will end up with constant broadcast traffic from the laptop as it looks for an IP. In actual fact a reservation will probably not be required since a Windows box will always request the previous address when renewing a lease.

Could just be me but unnecessary broadcast traffic is my pet hate and I do everything to get rid of it.

But in all honesty, playing clever games with a router isn't going to solve your problem. You need to stand up to it.

Well, it was stood up to tonight. He resorted to violence. I have a fractured wrist and he has a broken nose.....

I just told him that if she's going to act like she lives here, she needs to help out - just a teency weency bit......He threw a punch..didn't connect..I threw a punch..twice...it hurt, but it got the point across...
I despise violence (but having boxing experience doesn't hurt)..UGH..so essentially nothing was accomplished tonight but having doctors bills...
